The Chiefs put cornerback Jacques Reeves on injured reserve Tuesday.
The veteran defender has been dealing with a hamstring issue that kept him out of the Chiefs' 27-24 overtime victory at New Orleans on Sunday. Kansas City plays San Diego this Sunday.
Reeves has started 34 of the 90 games he's played in the NFL, but he stepped away from the game for two full years in his prime to tend to his mother, who underwent a liver and kidney transplant last September.
She died on July 26, the day the Chiefs reported to training camp.
Reeves proved to be invaluable when starting cornerback Brandon Flowers and backup Jalil Brown went down with injuries early in the year. Both of them are back now.
